Specification of Letters Patent.

Application led April 24, 1916. Serial No. 93,238.

To all whom it may concern.'

Be it known that I, GEORGE L. ROWEKAMP, a citizen of the'United States, residing at Vinona, in the county of Winona and State of Minnesota, have invented certain new and useful Improvements in Vapor-Generating Burners, of which the followingis a specification, reference being had yto the accompanying drawings. p

This invention relates to devices for gener,- ating inflammable vapor or gas and burning this vapor or gas, and particularly to devices peculiarly intended for generating infiammable gas or vapor from gasolene or like hydrocarbons.

The general object of the invention is the provision of a'mechanism to this end, so constructed that it may be used in connection with all hollow wire lighting systems and which is capable of being used with gasoleney lamps, lanterns, stoves, or in a large variety of other circumstances.

A further object of the invention is the provision of a generator and burner of this character wherein the generator is kept constantly heated and in a condition to generate gas and wherein the mere opening of communication between the generator and the burner will immediately cause the ignition of the gas issuing from the generator to the burner.

A further object of the invention is the provision of a very simple `mechanism to this end which may be readily taken apart for cleaning and readily assembled, and wherein provision is madefor a very delicate regulation of the torch' or auxiliary burner which heats the generating chamber and of the gas passing into the main burner.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein:

Figure l is a top plan View of a gas generating burner constructed in accordance with my invention;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 1; y

Fig. 4f isa section on the line L1--4 of Fig. l;

Fig. 5 is an elevation of the valve 37 and its actuating means; and Y Fig. 6 is a View showing my device adapted for heating.

Referring particularly to Fig. 2, 10 designates the generating chamber which consists of a cylindrical vor tubular member closed at its opposite ends, this tubular member being' in practice about two inches long. At one `end this tubular member or generating chamber is formed with an upwardly extending nipple 1l from which extends an arcuately bent pipe l2 engaged with one branch of a T-coupling 13. The other branch of this T-coupling is engaged with an arcuately bent depending pipe 14: which constitutes a shade support. The upper branch of the T-coupling 13 is connected to an upwardly extending tube l5 which at its upper end has screw threaded engagement with a union 16 provided with a reducing coupling 17, the union providing means whereby the pipe 15 may be'connected to the coupling on the usual hollow wire 9 or feed pipe leading from any source of supply. The interior of the tubes 15 and 12 are filled with asbestos packing, designated 18, this packing extending down into the chamber 10. Just below the nipple 11 the chamber 10 is provided with a downwardly extending nipple 19 normally closed by a plug 20.

vThegenerator l0, relativelyadjacent the nipple l1, is provided with the upwardly extending nipple 20 having an upwardly extending relatively small pipe 21 which at its upper end is connected to a T 22. From this T extends a downwardly curved pipe 23 which discharges against the generating chamber 10. Preferably a hollow wire, as it is called, or a small tube, of copper or other like material and designated 24, is disposed within the tube 21 and extends upward into the T 22 and extends 'through the torch or auxiliary burnerr tube 23. This tube 23 is provided with one or more small intake openings 25 Awhereby air y.may be mixed with the gas passing through the tube 24.

Controlling the passage of gas through the tube 24 is a needle valve 26 which passes through'a tubular valve guide 27 attached to one end of the T 22 and through a gland `nut 28 connected to the hub 27. The stem of the needle valve is provided with a handle 29 whereby the needle valve may be manipulated to decrease or increase the amount of gas iiowing into the auxiliary tube 23. The members 2l and 28 together constitute a torch discharging with considerable pres- Patented Feb. 13, 1917. 4

sure against the wall of the generating cham- Y ber and heating the contents of the generating chamber to thereby cause a vaporization of the liquid fuel passing into this chamber by way of the asbestos wick 18.

On the opposite end of the chamber l0 from the nipple ll is an upwardly extending nipple 30 from which extends an upwardly extending tube 31 engaging at its end with one branch of a 'l' The opposite end of this 'l' isengaged with an upwardly and then downwardly curved burner supporting pipe 33 whichr at its lower end carries any suitable burner, as tor instance, the mantle 34, this mantle being held in placey by means of supporting wires 35. YWithin the tube 3l there is disposed a generator pipe 36, and controlling the passage through this generator pipe is a longitudinally movable valve 37, the outer end of which is operatively engaged with a shaft 38. This shaft is slightly cranked on one end, as at 39, anda rotation of tnis shaft willA therefore operate to shift the valve 37 in one direction or the other toward or Jfrom the generator pipe and to very delicately control the amount et gas passing through this pipe.

The shaftv 38 is mounted in a guide tube 40 operatively engaged with a nipple al. The shaft passes through this guide tube and engaging the end of the guide tube is a gland nut 42. The extremity of the shaft 38 carries upon it the yoke or'lever 43 connected to chains let whereby it may be operated. The T 32 has an air intake tube 46 whereby air may be admitted inte the interior of the mixing chamber constituted by the T 32, the

Vmixed air and gas then passing through the mantle.

Inthe operation oi' this invention the liquid fuel passes down to the wick 13 and soaks this wick and this wick carries the liquid fuel into the generating chamber l0. The gas passing through the auxiliary burner tube or torch 23 is continually burning and g'ves a very small blue 'llame which is directed against the generating tube l0. This small flame ejected from the pipe 23 is suilicient to cause the vaporization of the liquid fuel entering the generator so that the generator is always iilled with gas. Now it it be desired to ignite the gas in the burner or mantle, one or the other of the chains 44 is operated which retracts the valve 3T and gas can pass from the generator out through the burner pipe 33 to the burner, as for instance, the mantle 34. The extremity of the pipe 23 is disposed relatively adjacent the mantle or burner and as a consequence will ignite the gas issuing from the burner pipe 33. Thus there is no necessity et lighting this gas by any extraneous means. Simply opening the valve causes the gas to ignite and the closing orn the valve cuts off the supply of gas to the burner. Theamount of lame directed against the generator may `enables me to secure a light of from one candle power to four hundred candle power and thus it is possible to have either an exu tremely bright light or a very dim light, as may be wished for, depending upon the extent to which the valveis opened.

lVhile I have illustrated this device as applied in connection with a mantle and in a lighting,` system, I wish it understood that it may also be used for heating systems, as for instance, in connection with a stove by changing the form ofY burner. Thus in Fig. 6 I have shown my device adapted to a heater. F or this purpose the construction is inverted as illustrated inthis figure. In this figure I' have already shown the relative positions or the burner tube 33 and of the blow or glass tube'23. The burner 34a in this case is a star-shaped burner and the blow tube 23 terminates between the arms of this burner. Otherwise than as thus indicated, the construction is the same as that illustrated in all the other figures.

Having described the invention, what I claim is:

l. In a gas generating burner of the characterk described, a generating chamber comprising a short section of pipe closed at its ends, a supply pipe having'one end entering the side wall oi' the generating chamber adjacent onc end thereof', a pipe extending outward from the middle of the generating chamber and having an extension leading therefrom and discharging against the exterior of the generating chamber, said pipe constituting an auxiliary burner or torch, a valve controllingV the passage through the auxiliary burner, a. mainy burner pipe extending outward from the side wall ofv the generating chamber and bent upon itself and extended toward and in a plane approximately parallel to the auxiliary burner pipe, ay burner mounted on the end of said burner pipe, a valve for controlling passage of vapor from the generator into the burner pipe, and an air inlet nozzle in the burner pipe between theburner and the valve, the auxiliary burner pipe being disposed in relatively close relation to the main burner whereby the main burner may be ignited from the auxiliary burner.

2. In a gas generating burner, a generating chamber comprising a short section of pipe having a relatively small bore and a relatively thick wall and closed at its ends, a U-shaped pipe, one end of which is'connected to the generating chamber adjacent one end thereof and constitutes a supply pipe, a wick disposed in the supply pipe and extending into the generating chamber, the other branch of said U-shaped pipe constituting a support for a shade, a pipe extend ing outward from the middle of the generating chamber andv having an extension leading therefrom and discharging against the exterior of the generating chamber and constituting an auxiliary burner or torch, a valve controlling passage through this pipe, a main burner pipe extending out from the side wall of the generating chamber adjacent the auxiliary burner pipe and bent upon itself and extending toward the auxiliary burner pipe and in a plane approximately parallel thereto, a burner mounted on the end of the main burner pipe relatively adjacent the extremity of the auxiliary burner pipe, and a valve controlling the passage of the vapor into the main burner pipe, said main burner pipe being formed with an air inlet between the Valve and the main burner.
